Gents,

I would like to get some company for my MSI GE70 gaming laptop (I7-3630QM quad core processor, NVIDIA GTX 660M, Intel HD 4000).

(A) Beginning with the GPU's, I would like to pursue either:

(1) AMD HD 7970 with 2048 shading units / 3789 GFlops (https://www.techpowerup.com/gpudb/296/radeon-hd-7970.html)

(2) NVIDIA GTX 680 with 1536 shading units / 3090 GFlops (https://www.techpowerup.com/gpudb/342/geforce-gtx-680.html)

(B) Keeping in mind one of the two above GPU's being part of my future configuration, the desktop units which seem attractive at the moment include:

(1) Apple Mac Pro 3.1 (Early 2008) A1186 with 2 x Intel Xeon Quad-Core @ 2.8 GHz and CPU rating 5365 as per http://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+W3530+%40+2.80GHz

(2) Dell Precision T5500 Workstation with 2 x Intel Quad Core Xeon E5520 @ 2.27GHz and CPU rating 4458 as per http://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+E5520+%40+2.27GHz&id=1243

(3) Dell Precision T7500 Workstation with 1 x Intel Xeon X5660 @ 2.80GHz and CPU rating 7998 as per http://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+X5660+%40+2.80GHz

(4) HP Z400 Workstation with 1 x Intel Xeon Hexa-Core X5650 @ 2.67 GHz and CPU rating 7594 as per http://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+X5650+%40+2.67GHz&id=1304

(5) HP Compaq 8100 Elite Minitower with 1 x i7-870 @ 2.93GHz and CPU rating 5475 as per http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7+870+%40+2.93GHz&id=832

(6) HP Z400 Workstation 1 x Intel Xeon W3670 @ 3.20GHz and CPU rating 8515 as per http://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+W3670+%40+3.20GHz&id=1273

(7) HP Z420 Workstation with 1 x Intel Xeon E5-1620 @ 3.6GHz and CPU rating 9112 as per http://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+E5-1620+%40+3.60GHz&id=1210

(8) HP Z420 Workstation with 1 x Intel Xeon E5-1650 @3.2GHz and CPU rating 11708 as per http://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+E5-1650+%40+3.20GHz

After contacting an eBay seller based in Germany for item (4) above surrounding the wattage of the power supply in his item (4), he suggested that I pursue an Dell HP Z420 or HP Z800 so as not to have performance issues with the HD 7970 and his statement caught me off-guard.

Item (8) is slightly out of my pricing range but I can be patient if necessary for a deal. With capital controls in place since late June and not a single euro leaving the country, I am not in a position to grab something "tomorrow" but I am eager to enhance my arsenal once the capital controls are removed.

Just the other day I came across a sweet deal for an MSI GE70 with NVIDIA GTX 860M and Intel HD 4600 and which I could only watch due to capital controls.

Suggestions and thoughts most welcome!

It all depends on what you want to do.

Check out their stats by searching for them, and usually the Intel page for the processor is top link or close. If you want to do LLR on CPU, on processor feature, make sure it has at least AVX, better AVX 2. In a quick look at the listed ones, it looks like only the E5-16xx models would have AVX and even then, not AVX 2 (FMA). That would be systems 7 and 8.

The E5-1620 would seem roughly comparable to an i7-2600k, any systems you can compare to with that processor? I have no idea what pricing is like on used kit. The E5 would have more ram bandwidth from quad channels which never hurt, but the i7 could be overclocked. I'm running one at the moment at 4 GHz although it might suffer on bigger units.

Mack, thanks for the heads-up on the I7 2600. An example would be http://www.ebay.com/itm/252164435920.

Yes, the machine will be strictly for PrimeGrid with the CPU dedicated to LLR and the GPU probably to manual sieving (ex PPR12M).

Mac specific comments:

The mac pro is going to have a 225w limit on pcie cards, unless you go with an external power supply. The 7970 is likely to exceed this (sapphire did make a 7950). I have tried an external power supply with 2 r9 280x cards in a mac pro. I was able to get them plenty of power, but I had serious thermal dissipation problems. That being said, if you are brave enough to try the radeon bios editor, you may be able to declock it enough to fit in the 225w envelope.

I have two mac pro 3,1s with a 680 and 640 each. They are great a sieving, but that's about it:
http://www.primegrid.com/show_host_detail.php?hostid=488562
http://www.primegrid.com/show_host_detail.php?hostid=478753

Contrast those with a 2009 mac pro with a detuned r9 280x:

(The rac for this machine is abnormally low, it has 4 pending WR units which therefore haven't been counted)

General comments (I like your option 7, with a 7970, and turn it loose on gfn):

Where are you looking to get your horsepower, cpu or gpu?

I'm not the cpu expert, and I typically look at them as something to keep my gpus fed :) That dell with the e5520s has the same processors as my 2009 mac pro (linked below). They are not fast. They are faster than the 2008 mac pro cpus. On a good day, it can finish an sr5 task in 13.9 hours, a trp in 30.9, a woodall in 132.9, and a pps-mega in 4.5, with all cores running.

Anecdotally, if the cpu cache doesn't scale proportionately to the number of cores, having those extra cores may not help performance proportionately.

On the gpu side, I have a bit more experience.

The 7970 will be great at GFN (as will any tahiti-based card). Meh at sieving.
The 680 will be great at sieving, and meh at GFN (afaik the only prime-finding gpu app we have).

The 7970 is going to draw more power, up to 250 watts, more if you get the ghz edition. The 680 will get up to around 190 watts. (per our friends at wikipedia).

Are you looking at closed or open shroud designs? An open shroud will empty the tdp of the card into your case. This will make keeping everything cool, including the gpu, harder.

Reference 7970 and 680 designs are closed-shroud, although other manufacturers have produced open-shroud versions. You can find a ghz edition in closed shroud, but its successor, the 280x, only comes open shroud that I have found.

Speaking of tdp, make sure the power supply in the target system(s) is up to the task (hence the comments referenced below). If you go with a 7970, and have a 100w cpu, that's already 350w, not counting all the other stuff in the case. Anything less than a 450w power supply will be running at more than 80% capacity, all the time. OEM systems often have notoriously anemic power supplies. I have killed a 750w corsair and a 1200w rosewill power supply all in the last 3 months.

Apologies for rambling on, but hope this helps.

If you have the power supply to run it, and can find a case that it fits in and which can dissipate all that heat (375+ watts, open shroud), I have a love/hate relationship with these:

http://www.ebay.com/itm/Sapphire-Technology-Sapphire-Radeon-HD-7990-21207-00-50G-6-GB-GDDR5-SDRAM-/252190182469?hash=item3ab7b4cc45:g:IJIAAOSw5VFWQuKK

Or if you don't care about having a reference design:

http://www.ebay.com/itm/Powercolor-HD-7990-Devil-13-Edition-/331716076133?hash=item4d3bd1a265:g:gzQAAOSwAKxWU7Fu

With some patience you can get them for cheap. Getting a system that can run them, maybe not so much, unless you want to sacrifice cpu speed.

I threw one of these:

http://www.ebay.com/itm/COMBO-DP45SG-MOTHERBOARD-LGA-775-Q9550-QUAD-PROCESSOR-4GB-MICRON-DDR3-I-O-/262167018338?hash=item3d0a5f3b62:g:~noAAOSwyQtV2mrz

In a cooler master HAF XB, grabbed a 750 watt power supply, and used a hard drive laying around. I was able to get the whole thing up and running for less than $500 usd, and it powers a 7990 nicely.

Zimmer,

A huge thanks for the really good info and insights. Hardware is very daunting owing to the fact one has a huge variety of options and combinations. The personal experience you describe below is very helpful.

Anything I can do to help. I've made some mistakes along the way (which I hope I can help others avoid), but managed to cobble together a decent arsenal of crunching machines pretty cheaply.

The 7970 will be great at GFN (as will any tahiti-based card). Meh at sieving.
The 680 will be great at sieving, and meh at GFN (afaik the only prime-finding gpu app we have).

The 7970 is going to draw more power, up to 250 watts, more if you get the ghz edition. The 680 will get up to around 190 watts. (per our friends at wikipedia).



Just to add something to this mix - if you can get an unused or mint-condition (hard to judge that if it's been used, I suppose...) 580, then it might be cheaper than a 680 because of its age, and it outperforms the 680 at GFN (as ponted out by Van Zimmerman). The 6-series had its double-precision capabilities deliberately crippled by Nvidia, probably because as is still the case, they don't want their GTX cards to encroach on the territory of their Tesla cards.The 580 has got a higher power draw, of course, but then the initial saving (if you can get it...) might cancel out at least some of the higher electricity bills.

A 580 won't be able to use the new OCL2 app, but neither will the 680 according to Wiki. A 7790 supports OCL2, again according to Wiki, though, so that's another option if looking for slightly older cards is a preferable option; although if you don't consider using the OCL2 app a priority, because at the moment it's only used for n=17 MEGA, then the 7790 is perhaps irrelevant. Having said that, something else to consider is what OCL2 could/will be used for in the future. The 7790 is a bit of a quirk in AMD's range, because none of the other 7000 series, or even any of the 8000-series cards, support OCL2.

I wasn't even thinking about a 580, but you are absolutely right. I started down this path with only a couple of mac pros, and the power draw of a 580 is more than they can take, so I kind of put it out of my mind.

As far as the 680 and OCL2, I did successfully run it on a 680 on a mac as part of the gfn 3.2.9 testing.

http://www.primegrid.com/forum_thread.php?id=6464

Ocl2 on anything amd on a mac is a no go, at least for genefer.

Ocl3 performance on my amd tahiti chips was atrocious, and only marginally better than ocl2. Which brings up another consideration that you touch on. If you go 7790, you are going to be best at gfn-21 and gfn-wr, with a bias to the latter. In my experience, performance on the smaller units using ocl3 (or 2 for 17-mega) is going to be so bad in comparison that you will probably want to stick with n-21 or 22 (or go nvidia).

It is somewhat gratifying to crunch out a wr unit every 2 1/4 days or so. If you are hunting rac though, the 660,000 or so every 2 days (assuming your wus get validated) won't compare to what you can get with a 680 crunching pps-sieve.




Just to add something to this mix - if you can get an unused or mint-condition (hard to judge that if it's been used, I suppose...) 580, then it might be cheaper than a 680 because of its age, and it outperforms the 680 at GFN (as ponted out by Van Zimmerman).

The GTX 580 seems to support up to CUDA 2.0 .... is this a problem?

I think there's some confusion about the naming of the GFN OCL apps here. Because I forgot there was an "OCL3" app, see... and this doesn't make any sense if they're talking about which version of Open CL the app uses, because OpenCL 3.x doesn't exist; the very latest version is 2.1.

The 580 "only" supports OpenCL 1.2, but compute capability 2.0, which I think is the misunderstanding here

On the project preference page, OCL3 is not mentioned at all. But in a linked thread, all that's said is that OCL2 requires CC 2.0 (so that's a tick for the 580). No restrictions/requirements are mentioned about OCL3, but it does say that it's slower than OCL2, but has a higher b-limit... and that it "runs well" on Maxwell GPUs - which means a 9xx model (and a couple of the low/mid-end 7xx cards, strangely).

So the apps appear in BOINC and on your tasks pages (when running them) as OCLcuda (amongst other terms), but can be using a card which has hardware support for OCL1.x or 2.x, But as long as you have CC 2.x or greater on an Nvidia card, you can run all the apps, which are called OCL, OCL2, and OCL3, and it doesn't refer to the version of OCL which your card supports. Which is confusing. I haven't previously heard CUDA and OCL talked about as being so similar, or even the same - they're different languages (which obviously do very similar things...). AMD cards can't have CUDA because it's Nvidia's thing.

Wikipedia seems to sometimes equate the CC version to the CUDA version of an Nvidia card, of which the latest version to be implemented on GTX cards is 5.3. The PrimeGrid guide to the GFN apps doesn't say anywhere that the OLC3 app requires CC 3.x on an Nvidia card, though; again, it doesn't mantion any requirements at all for using OCL3 on a GPU.

That was confusing to write, so I've got no idea how it reads. In short, a 580 has CC 2.0, and so according to the GFN apps guide page, will run all of them. As Van Zimmerman has said, and I meant to imply, a 580 is still a great card for the longer GFN tasks. The minus is the power draw, and probably these days getting one with a price tag which fairly reflects its age.

To follow up on the GTX 580 vs 680 dilemma, do these cards still function when the monitor is off (or a black screen saver is activated)? Similarly, how is the power draw with the screen off or in black screen saver mode if the cards continue to function with their number crunching?

Being a laptop nut for 15+ yrs, I have lost my bearings on desktop units and hence for the silly questions above.

Edit: I have come across two deals involving an I7 2600 with GTX 580/680 respectively. (very much leaning towards the deal with the GTX 580 at half the price)

Yes they'll keep crunching with or without a monitor. Power draw is likely to be near enough the same.

Edit: I have come across two deals involving an I7 2600 with GTX 580/680 respectively. (very much leaning towards the deal with the GTX 580 at half the price)


If you're ever going to crunch larger GFN tasks, you do indeed very much want the one with the 580.

If at all possible, deactivate all screensavers from all sources (i.e. Windows and BOINC), and just turn the monitor off manually when you need to. If that's not possible then you really don't want any screensavers running at all, I'm not sure exactly how to do it now but you really just want the monitor to switch itself off, not the PC to go into some kind of hibernate/standby state.

Final question: for sieving .... 580 or 680? The latter has twice the gflops of the former but the difference between the two is nominal as per https://www.primegrid.com/gpu_list.php.

Rick, the GTX 580 is from EVGA with 2 Gb RAM. It is not the latest version marked as Superclocked.

Edit: GTX 580 Fermi architecture, GTX 680 Kepler architecture

From what i have experienced, initial overclock from factory makes no difference other than how gfn handles it. I severely oc my cards for pps sieve and under clock for gfn. I run until i get errors and go from there. Very scientific. I am sure others will laugh ha

Thank you to both of you.

Final question: for sieving .... 580 or 680? The latter has twice the gflops of the former but the difference between the two is nominal as per https://www.primegrid.com/gpu_list.php.


I think the 680 definitely outperforms the 580 for sieving (because sieving relies on single-precision, like games). But you have to consider that the 580 is still "very good" at sieving, and you can barely buy DP performance as good as the 580 for the budget I'm imagining any more - I'm not sure whether the 780Ti ouperforms it (probably, but not massively), but unless you can afford a 970/80/80ti, or one of the TITAN series, I think a cut-price 580 is a no-brainer.

As always, other input may correct me. Or cause a massive fight ;)

Another idea is that IF (massive emphasis, there) you can get a 590 at a price which reflects its age, and you can afford the electricity bill (and indeed have the PSU for it), then that will be mighty at the larger GFN tasks, and anything else which requires DP. A common question about this is whether the two GPUs in a 590/690, etc. combine as one ultra-GPU in BOINC - they don't, they just do two tasks at once. And marginally slower then their x80 equivalents. The power draw of a 590 may be a bit too steep to live with in 2016, come to think of it.

I see the 590 is rated at 365W ... how many acres of solar panels would I need to cover its energy requirements? LOL!

Yes, that would be a unique card to opt for, and ONLY if you're sure.

I'm just wondering, can you not afford a 780Ti or a 980? If you could stretch to that then you wouldn't have to keep considering DP performance vs. sieving performance, and you'd have to erect far fewer solar panels ;)

The thing about the 580 is that if it's cheap enough, it's an incredible bargain. The 680 was aimed squarely at gamers, and is slower at large GFN tasks that a 580. So if I could have a custom vote in all of this, I would say "buy anything but a 680 as your GPU". For anybody except gamers on a budget, it's a waste of time and money.

Here's more of my opinions, which shouldn't really be treated as anything more than that:

A Sandy Bridge i7 (2600K - the non-K versions are about £1 cheaper) is the minimum that you want. I don't understand why people buy new Intel CPUs branded as i5s - they lack a third of the L3 cache, which really matters in PG. Then consider the fastest memory you can afford, and then work out which mobo will support them both and still be within your budget. The graphics card logically comes last, for PG, because if you've combined the above or newer then your card will definitely be supported. Again, my tip is to avoid the 680, it was and is a huge disappointment. If you can afford the above setup plus a 580, then you're onto a winner... again, as long as you get it cheap enough. If you've got some money to spend and you can stretch to having a 980 or even a 980Ti with the above, then do it before anyone else can post. The only reason you wouldn't do that is if you want to run long CPU tasks like SoB, PSP, or GFN 21/22 CPU; in which case the CPU requirements would change to a 4xxx i7 or 6xxx i7. That certainly doesn't sound what you're asking for, though. A 2600K which you can easily overclock to the XMP profile with cheap-ish memory will feed the most powerful of GPUs, providing you leave a (physical) core or two free. Also, on the CPU sieve challenges, you can forget about GPU crunching for a few days and boot it up with HT on, and watch the CPU munch on 8 WUs at a time :)

If you want DP, and you don't mind lurking on ebay until you get a deal, its hard to beat a 7990. Of course, at 375+ watts, they present other challenges, like heat dissapation. (sorry for the image size)

I like it ! Even like the nice green color you chose. I know it's hard to color co-ordinate these kind of projects. It's even Christmasy

Its the first milk crate I found rummaging around the barn this morning. Its got that 1960's hospital green thing going. I didn't have a darker one to go for a more apropos Chrismas color scheme, although, maybe I should add a string of lights. Why bother with LED fans when you can have static LED blinky lighting!

Temps are stable at 72/69C for GPU1/GPU2 (undervolted to 1.1). Certainly within limits, although I think I need more fans.

A STOCK INTEL HEATSINK AND FAN!!??

Seriously, I love that setup too. I especially like what looks like the all-copper heatsink fins over the actual GPU. I nearly bought a solid copper heatsink for this Haswell, but it came with a massive warning that if your system was vertical/tower, as mine is, then it breaks all the motherboard weight specifications by about a mile, and would risk bending/cracking it.

Edit: It was an earlier version of one of these, but for S1155 (I think, at the time) and all-copper, no aluminium.

All I have to say is one simple thing .... I am in the right project and especially the right team!!!! :-)

As for lurking around eBay, rest assured it is something I enjoy and I will keep an eye out for the 7990 for my own education for now. I am sure I can find a milk crate locally (in fact, I may have one and in the proper colour given the season and spirit).

After reading gazzyk1ns reply earlier today, I decided to forego the opportunity with the I7 2600k + GTX 580 (final price: 381 euro) and to be slightly patient to set aside a few more pennies so as to make my purchase as best as possible and especially involving the GPU.

Awesome set of messages and humour after Zimmer's photo below. :-)

I suspect Z-san is responsible for heating half of Tokyo (and is footing half the bill as well).

You need to connect the lights to the disk activity indicator. That way you can watch as your hard drive works and it will be a very random pattern.

Yeah, I know. I needed a couple of old boards cheap (for things like this...). Its a q9550 on an intel dp45sg I grabbed for $80, including memory. I only run cpu tasks on 2 cores to keep temps down, but its not like I'm missing out on any crazy performance (3 hrs. 20 min for a pps-mega unit).

The copper on the 7990 is for the center heatsink only, unfortunately. Each of the side heatsinks (on each gpu) is aluminum. The backing plate acts as a heatsink for the memory. Suffice to say you don't want to grab that thing right away after it has been crunching.

You need to connect the lights to the disk activity indicator. That way you can watch as your hard drive works and it will be a very random pattern.


Darn it, now I have to go find a 12v led light string in green and red.

I wonder if I could find variable ones and attach them to a fan header so as everything heats up they get brighter.

Thanks!

Astrophotography requires a LOT of patience since one is fighting all kinds of factors simultaneously (rotation of the earth, atmospheric transparency and instability, variable temperatures during the evening which affect focus during the extended exposures, humidity, winds etc).

In relation to birding, there are semi-apochromatic refractors which are used by birding enthusiasts. The Televue brand name is one such example.

After reading gazzyk1ns reply earlier today, I decided to forego the opportunity with the I7 2600k + GTX 580 (final price: 381 euro) and to be slightly patient to set aside a few more pennies so as to make my purchase as best as possible and especially involving the GPU.

I am really impressed with the GTX 780 Ti after researching matters earlier today and over the course of a few hours. The card really rocks for both PrimeGrid and Collatz (nice to have a backup project as a precautionary measure).

Someone had an early Xmas gift a few hrs ago with 3 ASUS GTX 780 Ti's with SLI for a mere 658 euros ($715) or about $238 a pop: http://www.ebay.com/itm/151916378421.

I am almost fed up to the back teeth of bird photography and identification, because my parents are obsessed with it. But those are properly good shots. Also, you have a wider diversity of birds there, than is the big mudsludge and man-made reservoirs of Eastern England.

I'm showing those to my parents and their friends, they'll be properly jealous.

I think that might be an ideal "balance" for a card. Well, especially as you've picked it out yourself.

Gents,

A friend brought to my attention an HP XW6600 Workstation with 2x Xeon E5450 CPU's running at 3.0 GHz (12M Cache, 1333MHz FSB) and 16 Gb DDR2 RAM. It has a 650 W power supply (80 Plus efficiency) and boasts 2 x PCI Express Gen2 x16, 2 x PCI Express x8 mechanical/x4 electrical and 2 x PCI 32-bit (legacy).

All of this for about $285.

Would I be able to get effective performance for one or two GTX cards given the current hardware? I would be looking to add a GTX 750 Ti and later proceed with either the 780 Ti or the 980 Ti.

Can the CPU's (8 cores, 16 threads) provide reasonable performance with either LLR or Sieve units?

I do not know if the DDR2 RAM can be upgraded to DDR3.

This sounds similar to some of the mac pro xeons.

Individual work unit performance on those cpus will probably not be great. But you do have 8 cores going, so that will make up for some of the individual core (lack of) capability.

As to GPUs, with 2x16 pcie slots (which may be 2x8 if you populate them both, but that's not a big deal for crunching) power is the only concern. Each cpu is rated for 80 watts, so there's 160 off the top right there. Both the 980ti and 780ti have a tdp of 250, and the 750ti has one of 60w. If you run 2 gpus, 160+250+60=470w. 80% of 650w is 520, which in theory you want to stay below for continued loads, which leaves 50w for other system stuff. I would think you'd be ok.

I run an old lenovo s20 workstation with a w3520 (130w tdp) and a r9 280x (250w) crunching for the past year or so on a 450w power supply.

Someone correct me if I'm crazy here.

Zimmer, many thanks for the feedback.

With respect to the GPU's, I can always stick a pair of 750 Ti's to get the total TDP down.

The item is overpriced at $285 and is literally less than half that amount in the US but with the shipping being prohibitive.

I think the power supply is 525w. My build philosophy has been to build around gpus, since they provide a lot more computing capability.

For something ridiculously expensive, and totally unrealistic unless I am willing to put a second mortgage on the house:

It does leave me saying "I have GOT to get me one of those" though...

Please remember to post benchmark results! LOL.

I agree that one should build around the GPU's.

Here is a much better buy: http://www.ebay.com/itm/151942752018 with a six-core W3680 at 3.33 GHz and DDR3 RAM.

I will check on the power supply and PCI-e slots.


I think the power supply is 525w. My build philosophy has been to build around gpus, since they provide a lot more computing capability.

For something ridiculously expensive, and totally unrealistic unless I am willing to put a second mortgage on the house:
https://www.youtube.com/watch?v=Jdm-Z8Z8mZo

It does leave me saying "I have GOT to get me one of those" though...


Put two on my credit card, please! :)

I loved seeing the Basket Case rig! I missed the updates in this thread while I was away on vacation. The great thing about the basket case it it ought to stack very well. You could have a whole cluster of these!

Check out the following gem with 24 cores (4 hexacore E7450's @ 2.40 GHz) with 4 PSU's at 1200W each:

http://www.ebay.com/itm/262116037732

As for the processor: https://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+E7450+%40+2.40GHz&id=2419&cpuCount=4

Less than $450 .... this thing should feast on the LLR projects.

Ancient CPU. No AVX. LLR performance is going to really suck. I estimate in total you'd be lucky to get as much output as a single stock i7-6700k.

Twenty-four hrs ago a Lenovo Y50-70 sold for 311 euro (only one bid) with I7-4710, GTX 860M, HD 4600 and 16 Gb RAM. I was almost in tears since the seller (in the UK) would not consider shipping to Greece.

The screen was dead and, hence, for the single bid and low price but I am sure I would have found a way around the display problem.

I have my eye on some I7-2600K units ....

Gents,

As a follow-up to Mackerel's excellent analysis elsewhere, see http://www.primegrid.com/forum_thread.php?id=6675&nowrap=true#93137, I started building my mini-farm.

Last night I picked up an i3 6300 (3.8 GHz) (99 euro), a 500-watt 80+ power supply (35 euro) whereas earlier today I picked up an MSI H110M PRO-VD mobo (47 euro). Tomorrow I will be picking up a Kingston Technology HyperX FURY (8 Gb DDR4, 2666 MHz, dual channel, dual rank) from someone locally for 30 euro (unused).

I have ordered three USB WiFi adapters from Hong Kong in anticipation of similar system purchases over the next few weeks (1.60 euro each).

For those with multiple mobo's in action, can I assume you have a single monitor handling the video and something like a 2- or 4-way VGA splitter/hub is used to direct the video from each mobo to a single monitor? I am not sure something can be directed to a portable laptop's screen for the odd moment that human intervention is desired.

Once I have this particular system up and running (i3 6300, MSI H110M Pro-VD, HyperX FURY DDR4 and MSI GTX 750 Ti), I will see about acquiring another two similar configurations whereas during late summer I will pursue an i7 4790k with MSI Z97 Gaming 5 mobo with either a GTX 780 Ti or GTX 980 Ti.

NVIDIA is supposedly planning to showcase the Pascal X80 series at some trade show next month with sales starting in May or June. If this does pan out, perhaps we will see a nice drop in pricing for the current stock of GTX cards (especially the 780 Ti/980 Ti which interest me).

Thoughts, suggestions and alternatives most welcome.

PS. I am trying to locate Mackeral's other epic message and where the i3 6100 really shines.

As far as I understand, with the exception of some Asrock motherboards, you might not be able to run the ram at rated speed without Z170 chipset. I haven't looked into what other mobos might do. That aside, that's a good price for the 6300. Was that a one-off price or normal?

I had some further discussion on another forum, and with a cheap Asrock and faster ram hack, an i5 could be cost effective also and may go ahead in power efficiency. But I'm not entirely confident in that as it relies on particular ram chips to be used.

If you want access to multiple PCs with one monitor, keyboard and mouse, you can get a KVM unit. These come in a variety of options. I have an ancient 4 port one supporting VGA and PS/2 connected keyboard/mouse only. More recently I got a 2 channel one that works with DVI and USB.

Alternatively, do you need direct access? My crunchers only need that to get set up. After that, I use VNC to access if needed. There is a small pain of having to move the box if I really do need physical access to it, but it isn't needed often once set up.

I was very pleasantly surprised with the 6300. I had the only bid and which I placed seconds within the close of the auction. A fellow bought it mid-January of this year and it is with minimal use. It is my understanding the kit cooler which comes with the 6300 is respectable.

As for the Z170, I am already keeping an eye on it since some are sold at very attractive pricing.

I had some further discussion on another forum, and with a cheap Asrock and faster ram hack, an i5 could be cost effective also and may go ahead in power efficiency. But I'm not entirely confident in that as it relies on particular ram chips to be used.

Speaking of i5's, 90 minutes prior to my purchase of the 6300, an i5 4570 sold for 105 euro. I missed placing my bid by about two seconds (I had a burp with my internet connection).

If you want access to multiple PCs with one monitor, keyboard and mouse, you can get a KVM unit. These come in a variety of options. I have an ancient 4 port one supporting VGA and PS/2 connected keyboard/mouse only. More recently I got a 2 channel one that works with DVI and USB.

Excellent. I will also look into the KVN units since I did overlook the keyboard.

Alternatively, do you need direct access? My crunchers only need that to get set up. After that, I use VNC to access if needed. There is a small pain of having to move the box if I really do need physical access to it, but it isn't needed often once set up.

I also thought about a software approach such as TeamViiewer but there is the initial manual setup. Once the first system is finalized, I will clone the disk for the other forthcoming systems so as to be up and running immediately and with minimal further intervention.

As an aside, Intel Xeon E5 2670's (2.60 Ghz, 20Mb cache) and with eight cores are being dumped en masse for about $65 on eBay at the moment.

Just a possible heads-up for anyone interested.

In a very quick look, they seem to be Sandy Bridge era so lacks FMA, but at least still has AVX. While the CPU seems to be cheap, I haven't found any low cost mobos they could go in. It was almost interesting to have a dual CPU setup just to say I have one as it has been many years since I had dual socket. But the mobos would kill the deal unless you're better at digging a cheap one up than I am. I don't think these make much sense for single socket unless you happen to already have a spare mobo ready for it.

The lowest dual CPU mobo I was able to find the other day was around $340. I will keep looking every so often in case I get lucky. Just thinking about sixteen cores and 32 threads makes the adrenaline rush hit the roof. :-)

On The CPU front:

http://www.theregister.co.uk/2016/03/22/tock_block_unticks_intels_clock/

...So bear in mind that the traditional Intel pricing may go a bit unusual in the next year or two, as they abandon their tick-tock cycle. For example, waiting for Kaby Lake to come out might allow you to buy a really overclockable Haswell (Devil's Canyon), or even two. Also, if you dive in and buy the latest and greatest when they go down to 10nm, I wouldn't expect to be able to trust a big overclock. I'm still disappointed that Skylake has hardware bugs, even if they've released BIOS upgrades to correct them. It doesn't fill me with confidence.

I say "...even two" because clearly you're planning lots of cores. But as Mackerel has pointed out, if they lack even AVX then lots of cores are going to be frustratingly slow, especially in challenges where there is obviously a time-limit.

It depends on what you want to do, really, I'd say that if you want to do PSP and/or SoB then you'll want AVX and FMA, because even with those features, SoB tasks in particular are still HUGE. But if you want to do billions of SGS WUs, then I don't suppose it'll make too much of a difference.

Don't forget how important fast RAM is, if you go for a fast CPU.

I realise you're sort-of aiming for the server market here, I'm just putting a vote in for a powerful non-Xeon, or two if the price is right. You definitely want AVX, again, as Mackerel has stated.

The earlier mentioned Xeons do have AVX, so not the fastest, not the slowest.

Skylake bug, largely not a problem in practice as the conditions required for it are very niche. Most bugs don't make headlines. I think this one got a bit more news as there were fears it would be as bad as the old FDIV bug which didn't have a fix.

Personally I'm debating if I should get a Broadwell-E when they arrive later this year. They wont be cheap, but if comparable to equivalent low end Haswell-E it would be on a par with a mid range OC Skylake + mobo.

Then again, it is starting to warm up now. I'm debating which boxes to turn off or otherwise optimise to run lower power than they do now. So maybe I wont be acquiring any more crunchers for a while. I might still have to get a Zen to play with.

This is a problem in the UK, isn't it? Jokes* about the weather always being terrible aside, after March it tends to go from freezing to boiling (in our terms). I might have a free fridge if I want it next month - if I accept it then it won't be for food, I might unscrew the door and point the coolest bit (i.e. lower back shelf) at the intake fan at the front of my PC. Hugely inefficient in cost, and I might singly bring global warming up three notches, but it might do my poor PC a favour. Which is the most important thing.

*Well they aren't jokes, it's true. But you live here too, so we know what we mean.

Yesterday, for most of the day the sun was out and the sky was mostly clear. Temps in my house increased rapidly and I had to open windows. It was the trigger for me to think about what I'm doing next. Today, rain, rain and more rain. But still not that cold. I picked up a pond (nothing to do with PC cooling!) and was moving it around in the rain in no more than a t-shirt. Only the moisture got to me after a while, not the temperature.

I'm in the finishing stages of an aquarium inspired PC cooling experiment. It'll be my first "serious" youtube video when done... there's a lot more work involved in making a video than I expected...

I'm looking forward to it.

If I can deconstruct a fridge and have a Dyson "fanless"* thing blasting cold air through the radiator, that would be great.

That would involve me having skills which I don't have, and also money which I don't have, though. Hard to get around those two key aspects.

*They quite clearly do have fans, but you know what I mean. No blades exposed. You could have one either side of the radiator, in a push-pull arrangement. I suppose £300 on fans alone isn't that bad if you've got a free fridge/freezer in the first place. When the fridge/freezer breaks down is when the cost goes up, I suppose.

Feedback and thoughts always welcome and, to this end, thanks for info below.

My primary goal is to dramatically increase my computing cycles via CPU's and GPU's. I ordered another MSI H110M Pro-VD in anticipation of a second i3 Skylake to be acquired at the first opportunity (6100 or 6300).

However, I would like to supplement my current i7 quadcore with a faster version thereof later this summer. If a small delay will mean the ability to pick up one or two i7 4790k's even cheaper, then it is something for which I can easily wait for.

With three i3's (6100/6300), my existing i7 3630QM and at least one i7 4790k later this summer (or even slightly later) plus a GPU for each of these systems, I will be in a very good position to be productive and to make a greater contribution to the group's efforts (vis a vis Z-san, Zimmer, Rick, Dave etc).

On a small side note, I am in a race against time due to the ESP Sieve possibly being suspended early fall. I flip tomorrow to Ruby and to Turquoise less than two months later. Jade is definitely doable by early September and the probable suspension but I have a serious fetish for those gorgeous blue Sapphire badges. :-)

Further to your excellent post (http://www.primegrid.com/forum_thread.php?id=6675&nowrap=true#93137), any comments as to the optimal amount of RAM and/or its distribution across the 2/4 slots?

Quantity of ram I haven't tested. The tasks aren't very big and for a dedicated cruncher, I think even the smallest modules we can buy are more than enough. For instance, on DDR4 the smallest modules I see are 4GB. We don't need that much, but we have to buy two to run in dual channel mode.

As for which slots, I would just follow whatever the mobo manual recommends. For 4 ram slots, I think this is typically slots 2 and 4 where 1 is closest to the CPU. At least for my MSI Skylake mobo, I did find 1 and 3 slightly less stable than 2 and 4 when really pushing the ram.

I haven't tested to see if there is any performance difference in slots. There shouldn't be, but could be something to test out. I was about to try overclocking the ram in one system so I could possibly try that.

I just checked Kingston's website and all of the 4 Gb modules are single rank. With the 8 Gb modules, they have both single and dual rank.

It comes down to how much you want to spend to optimise performance. Do I want to get extra modules, or much more expensive modules to get 2 rank? Or do you figure that into the overall value equation and use a weaker CPU to balance better? No easy answers.

Oh, the trend for 8GB modules seems to be moving towards single rank too, so it may end up that only 16GB modules will be dual rank, and going quad 4GB modules would work out cheaper. For example, on G.Skill side, the Ripjaws V 2x8GB 3200C16 I have (don't have exact part right now) are dual rank, but I hear their 2x8GB Trident Z seem to be single rank.

When searching on the Corsair website for similar info, I came across a 2014 article with all kinds of performance testing from 2014 and which suggested that rank has very little impact on performance. I will dig up the article with link later.

I will decide today whether to pick up a single stick (8 Mb, 2666 MHz) from someone who is selling it for 30 euro (brand new item) and which is dual rank or pursue 2x4 Gb single rank. There is the issue of dual channel which suggests the latter.

Yeah, unless my memory has gone extremely bad (don't discout that...), you have to have two modules for dual channel RAM. One of the first pages in your Mobo booklet will tell you which two banks to use. It would be a bit silly to ignore that. Two modules of average RAM will far outperform one bank of fast RAM. If you can afford something which supports quad-channel RAM, then the same applies, the bottleneck for the last few years has been the speed of RAM and amount of channels, not the clock speed of the CPU.

No matter how fast it is, don't buy one bank of RAM, assuming it's a PG crunching machine.

If you can afford a modern machine which supports quad-channel RAM, then it'll outperform two or three i3 and perhaps i5 machines using average dual-channel RAM. I've got no real idea why people buy that kind of machine for PG; RAM and CPU cache is everything, assuming you've got a half-decent CPU.

Again, unless you just want to run a billion SGS or PPSE WUs, in which case just buy anything cheap.

See midpage and thereafter: http://www.corsair.com/en-us/blog/2014/september/ddr3_vs_ddr4_synthetic

If nothing else, dual channel is way more significant than dual rank if one is faced with a decision between these two options.

The best way to think is not which one variable is more important than the others, as they all contribute. I'd simply look at it this way. Consider the speed, multiply by number of channels, and account for rank. You want that to be as high as possible without spending silly money.

Overall, ram channels is likely to be most significant. 2 is double 1, that's a big difference. Ram speed, get faster but don't pay silly money. Rank is harder to quantify. From my testing it looks like single rank performs about 0.8x that of dual rank. So all else being equal, dual rank 2666 would be about same or even slightly faster than single rank 3200. I once benchmarked against someone with ram running at 3700, but it was single rank. My box with 3200 dual rank ran a bit faster.

Quad channel ram isn't as simple a "win" as it may seem. Those systems supporting it typically come with more cores. So an 8 core quad channel ram system is comparable to two quad core 2 channel ram systems. The possible sweet spot would be 6 core 4 channel systems.

The i3 is dual core dual channel, so that is least memory limited of the lot. Sure, only two cores can't do that much work, but with cost optimisations you could build these very cheaply. The key is, you don't need high performance anything to go this route so cost is minimal.

For bigger tasks, cache makes no significant difference. So in that sense, get the i5 not i7 and put the money elsewhere.

Oh, all those comparisons about how bandwidth, rank or whatever scales, and showing no big effect. Those are done for general tasks. We're looking at a specific task here which does benefit from it.

Kinda... a low end X99 mobo with i7-5820k is comparable in cost to a mid range Z170 board + i7-6700k. So not too silly... then again, a low end Z170 board + i5-6600k overclocked similarly would perform like the 6700k so would cost a fair bit less.

Well, it took a little longer than I expected but I managed to locate DDR4 RAM (4Gb modules) and which is dual rank: Crucial Ballistix Tactical 8GB Kit (4GBx2) DDR4-2666 UDIMM CT8060667.

According to the manufacturer, the memory is also quad channel and compatible with the MSI H110M-Pro-VD.

Edit: Not at 2133 MHz but 2666 MHz. Not an issue.

Nice find. Didn't think dual rank 4GB modules existed. Wonder if they do a faster version?...

edit: doesn't look like it...

edit 2: ordered a set from amazon. If my previous testing is correct, it should be faster than single rank 3000 I'm using in a system now.

looking also in a system upgrade.

My current desktop system is now 8 years old. Q6600 @3.5ghz, cooled with a custom water cooling (big radiator, could mount 12*120 fans on one side, but passiv is enough).

I've got my eyes on the 5820k. With my custom water cooling, overclooking should not be a problem. The overclooked Q6600 generats a good amount of heat.

Prices in Europe are not nice, but yeah, can't chance that ...

Prices in Europe are not nice, but yeah, can't chance that ...

European pricing is indeed prohibitive. I use eBay most of the time since pricing is much lower than what it is in Greece, partly due to the high VAT (at 23%) but mostly due to gauging.

Sellers from Germany, France and Spain seem to have the best pricing around with very reasonable shipping charges (esp. Germany and France). UK pricing is also competitive but the shipping is somewhat prohibitive and which invariably kills any purchase since the total amount (purchase price and shipping) takes off.

Whenever possible, I buy from China or Hong Kong since they will compete in pricing and also offer dirt cheap or free shipping. The only problem is the 30-day or so delay for something to make it here.

In relation to the DDR4 memory described below, I was pleasantly surprised to find a kit from a local online outfit for 2x4 Gb sticks for 49 euro (VAT included) plus five euro for the courier delivery and COD payment. The next best deal was from Germany at 54.xx euro plus 9.95 euro shipping.

Nice find. Didn't think dual rank 4GB modules existed. Wonder if they do a faster version?...

I sent an email the other day to G.Skill asking about dual channel dual rank memory in 4 Gb sticks and at 2133 GHz (I requested part numbers if such memory was available).

I just received a reply with the following:

F4-2133C15D-8GNT (without heat spreader)
F4-2133C15D-8GVR (with heat spreader)
F4-2133C15D-8GRR (with heat spreader)


I just took a quick peek at their website and I do see the reference to dual channel but nothing about dual rank.

Just a heads-up.

What I meant was, are the people reading that e-mail address the same as those running the forum.

Anyway, by chance discussion in two different forums, I ended up testing an i5-6600k fixed at 3.5 GHz with single rank ram at 2400 12-14-14-35, 3000 15-17-17-35, and 3600 slack timings (they're not to hand). In short, 2400 to 3000 increased Prime95 4096k 4 worker throughput 20.6%, for the 25% clock increase. Nice boost there. Going from 3000 to 3600 gave 3.3% throughput increase for 20% clock increase. Diminishing returns. So it seems for quad Skylake at 3.5 GHz, 3000 ram gets you most of the performance. I might try to fine tune that some time.

I think this also showed a potential error in my earlier estimates in how rank influences things. I suspected my results were slightly over-estimating the ram bandwidth required. I didn't allow for the change in throughput being non-linear depending on the balance between ram and cpu. It only approaches linear if you're really limited by one or the other, so I'll have to retest that and see what it does.

Wish I didn't order that dual rank ram from Amazon on free delivery now. Dispatched today with an estimate of 2nd, which is a weekend and as it is to my work address I'm not likely to see it until Monday unless they're early.

Ram has arrived! So they were early after all...

In a quick visual inspection, I can only see ram chips on one side of the board which isn't a promising sign. Can't actually test them until later tonight.

Mine should be here Monday. Earlier today I received the i3 6300 and 80+ certified power supply. The MSI H110M-Pro-VD should be here mid next week whereas the USB WiFi adapters from Hong Kong at some point around mid-April (I will use ethernet for now).

Single rank according to Thaiphoon Burner. Haven't benched it yet. Guess the Crucial web page was incorrect.



If anyone is checking the part number, there's an extra 2C after BLT on the webpage and also the kit packaging. Presumably the reported part number here is for a single module.

Huge relief at my end ... part number BLT2C4G4D26AFTA: http://www.vnp.gr/ypologistes/exartimata-i-y/mnimes-ram/crucial-8gb-ddr4-2666.html

I will confirm upon receipt of the RAM over the next few days when it should be here.

Mackeral,

Something is not right. Your part number should also be dual rank. See http://www.crucial.com/usa/en/blt4g4d26afta.

Edit: the presence/absence of "2C" seems to be a USA vs EU thing.

Benchmarking seems to confirm it is single rank. Most likely thing here is Crucial got their web page wrong.

In other news, there is another possible cruncher idea. I'll list UK prices only, but Xeon E5-2670 are under £90 a pop on ebay, even less from US. That's 8 cores 16 threads at 2.6 GHz base, 3.3 GHz turbo. Supports AVX but not FMA. They support dual sockets. There are no cheap mobos but there's a new Asrock for around £250. It takes standard DDR3 ram. Some more effort might be needed on PSU as it looks like it needs TWO 8 pin connectors for the mobo (one for each CPU).

I'll work out various things like an estimated bang for buck and performance per watt later, but very roughly I estimate the raw crunching capability as equivalent to a quad core Skylake at 6 GHz, or a 6 core Haswell-E running at 4.6 GHz as far as prime crunching is concerned. The Haswell-E comparison is interesting as that could be attainable with overclocking, and a 5820k + mobo would work out similar in cost to 2x Xeons + Asrock mobo.

I was eyeing some of the xeons out there. My biggest concern with really packing in the cores is the core/ram channel ratio.

8 cores/quad channel ram may introduce bottlenecks similar to 4 cores/dual channel, at perhaps an increased cost.

I was starting to think about a 5820k on an x99 board with ddr4 that can do quad channel. Crunch on 4 cores, and feed gpus with the other two.

The ram demands probably wont be as bad as it seems. Although it is a lot of cores, it is not a lot of individual clock, and lack of FMA reduces that demand further. The base clock of 2.6 GHz isn't much, and factoring in my previous estimates, it might behave like a 1.5 GHz Skylake core. But you have 16 of them! Two CPUs + mobo will come to a similar cost as a 5820k based system. So you could get higher performance with an overclocked high end Haswell-E, but the Haswell-E solution will work out higher cost too. My initial estimates are that even standard DDR3 wont bottleneck this CPU, assuming quad channel per CPU at 1600. The asrock mobo even supports 1866 apparently which is technically an overclock.

Also for software that doesn't take advantage of FMA, the amount of performance would be relatively higher.

I still need to dig deeper into the value proposition here, but it is so different than single socket I want to try it to find out!

That dual socket thing gets expensive fast.

For my two "modern" xeons, both single socket
http://www.primegrid.com/show_host_detail.php?hostid=496359
http://www.primegrid.com/show_host_detail.php?hostid=497081

I have not been thrilled with the performance of the (newer) xeon-based systems I have.
I have them crunching on 3 cores, as I do my i5-6500. (http://www.primegrid.com/show_host_detail.php?hostid=503116)

All technically 3.2 ghz, although the i5 runs at 3.4.
The i5 completes an ESP in around 34-36000 seconds and a cpu gfn20 in around 109000 seconds.
The xeons complete an ESP in 51-60000 seconds and a cpu gfn20 in 248-251000 seconds.
My i3-4130 completes an esp in 40-52000 seconds and a cpu gfn20 in 113-130000 with both cores loaded.

Granted the e3-1225v3 isn't the best processor out there, but it does have avx2.

The e5 you reference has slightly more cache per core, (20mb for 8 cores vs. 8mb for 4), although I'm not sure how much a difference that would make.

As a complete aside, anyone have any experience with a 5775C?

I have a i5-5675C. L4 cache means it doesn't matter what ram you use up to 4x 4096k FFTs. L4 bandwidth comparable to ideal dual channel 3200. CPU not great overclocker. I couldn't stabilise 4 GHz without looking at turning up the volts. IPC seems 6% LESS than Haswell. No idea why.

Less? Strange.

I'm beginning to think the "lots of cheap little i3 machines" is the way to go.

Warning: wall of text alert! In short, Xeons still interesting in performance level, as expensive as other higher end consumer options once you get a system around it.



Ok, I've done some calculations for performance per watt, and bang for buck. This does rely on many assumptions and I am basing these on what's more important to me.

I'm going to compare 3 hypothetical systems.

1, i7-6700k at stock (4 GHz, 4 cores) £290
2, i7-5820k at stock (3.3 GHz, 6 cores) £330
3, E5-2670 x2 (2.6 GHz, 16 cores) £170 for two

Clocks given are base clocks, as I'm assuming under full load that is what they'll run at. I've built a hypothetical system around the above, picking a low cost mobo for each (for the Skylake system, I went Z170A, although non-OC boards would be cheaper).

Ram for #1 is 2x8GB DDR4-3200 for £100, 2 4x4GB DDR4-3200 for £100, for #3 8x4GB DDR3-1866 non-ECC for £120. I'm assuming the latter runs at 1600 but it costs no more to get the higher speed. Note I went for 8 sticks, to allow both CPUs to run at their full potential with quad channel memory. Running less will cripple it and negate the point of considering such a system.

Cooler wise I'm assuming high end air at £50 each, so double for the two Xeons.

Common components will be a Corsair RM series, probably 750W at around £100, allowing same again for a random case, and £40 for a basic 120GB SSD to get an OS on. I'm not including OS cost or GPU, the assumption being these systems will be used for compute heavy tasks only that do not depend on GPU availability.

Metric 1, performance per watt. The Xeons only support AVX. I will assuming all CPUs here are equal in IPC, which is probably not true, but I don't have personal data in this respect. Further assuming it isn't ram speed limited, you can simply multiply clock and cores. No surprises, the dual Xeons win by miles here, at over double the combined clock of the Haswell-E, which in turn is a bit higher than the Skylake system. Factor in the CPU TDP (ignoring rest of system power), it isn't so clear cut. By my scoring system, 6700k scores 176, dual Xeons 181, Haswell-E 141. Although the Xeons have a lot of performance, they also use a lot of power, which balances out. Haswell-E loses out here.

To complicate matters, what about applications supporting FMA, which the Xeons lack? In previous testing, Haswell has 1.5x IPC compared to Sandy Bridge in Prime95 like tasks due to FMA, when not ram limited. This swings the ball towards the newer i7 systems. Here Skylake still scores 176, Haswell drops to 124 due to its slightly lower IPC I measured at 14% in this application, and the dual Xeons are down to 106.

This still isn't the whole story. Note I said "when not ram limited". They are. Again in the past I've done testing on the performance drop due to ram bandwidth starvation. This is why I went for 3200 ram for both i7 systems, instead of the agonisingly slow 2133 standard. Anyway, figuring in efficiency loss from ram bandwidth starvation, the scores are then 150, 122, 98 respectively. Haswell-E and Xeons didn't drop much, but they started so much lower that even the bigger drop of Skylake didn't lower it to their level. 

Power efficiency conclusion: for running costs Skylake wins at FMA supporting applications. For AVX, the Xeons are still competitive. Note these results may shift once diluted by system power usage. I can't model that in any useful way.

Metric 2: bang for buck. I can total up the previous values and reach a system cost. The Haswell-E and dual Xeon setup come within a fraction % of each other at £885 and £883 respectively. The Skylake system is a bit cheaper at £770. I can divide these values into the previously calculated effective CPU performance to get a bang for buck rating. In AVX applications, for the 6700k we score 21, for 5820k 22, and dual xeons come in at a whopping 47! Over double the other two. What about FMA? Back to Prime95, in peak scenario not limited by ram, we get 21, 20, 28 respectively. So the Xeons still take it here. And what about when ram limited? 18, 19, 26.

Bang for buck conclusion: Dual Xeon wins outright here with the i7's fighting over 2nd place.

So, my overall conclusion would be, if you don't care about power costs, just get the dual Xeons for their compute potential. If running costs worry you more than up front, then the Xeons are still a good choice for non-FMA applications. With FMA support, go Skylake. Chances are for most, the running costs are much less significant than up front costs.

If I still want to get a dual Xeon system to play with, I'm looking at the best part for £900 for the parts above. I'm not sure I want it that much! This is a classic case of "I could, doesn't mean I should!"

Oh, remember I said about using ECC ram possibly? That isn't so cheap. I haven't scoured for the lowest cost, but they're starting £24 a stick on Crucial's website so that would add an extra £72 onto the Xeon build if you wanted it.

I should finally add, the value of the i7 systems could be increased by overclocking them which you can't do with the Xeon. For my uses I'd get better value from the i5-6600k and overclocking it instead of the i7-6700k with or without overclock.

I was starting to think about a 5820k on an x99 board with ddr4 that can do quad channel. Crunch on 4 cores, and feed gpus with the other two.


Assuming you use quad channel 3200 ram without overclocking the CPU, this should not be significantly ram limited running 6 cores. You would have to overclock it to 5 to 6 GHz to drop the efficiency down to Skylake levels with the same speed ram (but obviously half the channels).

Note I am assuming use of fast ram here, unlike the i3 system which uses standard slower ram. It is a balance between total CPU demand and ram bandwidth, not as simple as cores per channel.

Using newegg prices (usd)

5820k $390
asrock oc/formula 3.1 $330 (drool)
4 sticks CMD16GX4M4B3200C16 $240
$960

i3-6300 $124
asrock z170-pro4s $110
2 sticks F4-3200C16Q-16GVK $50
$274

Part of the problem will be if I go the 5820k route, it will be the best system I have, so I 'll be "forced" not to skimp. I could get a cheaper motherboard, and I might find cheaper qualified memory. And I might convince myself I don't need another haf xb evo to fit all the gpus I'll need to get to keep it fully populated.

With the i3, I can justify geting cheapo cases and power supplies (don't need that $400 ax1500i, that $65 cx500 is probably good enough). All in, I could get at least 3, and probably 4 i3 systems, and even with 1 gpu each, I'll have as many of them, too. And I don't have to get them all at once.

Of course, looking at the oc/formula reminds me of why I don't seem to get bad cpu tasks on my mac pros-ecc memory. That might be a motivating factor to go xeons, although I wonder how much some ddr4/3400 ecc would cost. And a whole 'nother set of memory benchmarks, since it will be a bit slower :)

This is precisely the route I am following. Earlier today I received MSI's H110M Pro-VD mobo (50 euro with shipping included) and all that remains is for the RAM to arrive before I will be up and running.

Also, we now have multiple integrated GPU's (HD 530's) via this route. I will start with a GTX 750 Ti in each system.

I will post some results once I am up and running.

Benchmarking seems to confirm it is single rank. Most likely thing here is Crucial got their web page wrong.

Once I am up and running with results at my disposal, I will contact Crucial. This is false advertising.

If I were to remain with single rank, there are cheaper options available.

Zimmer,

I think we have a hidden gem lurking around, namely the i5 4590S. Its TDP (at 65W) is slightly more than the i3 6100's 51 W but now with four cores rather than two and which will easily make up for the difference in the base speed (3.8 GHz vs 3.0 GHz).

The value for a used i5 4590S is only slightly higher than that for the i3 6100 by about $30. You can get a very basic mobo (MSI Z97 PC Mate) for about $65.

We may need to lean on mackerel for an opinion as to whether those extra two cores, albeait at at a lower clock speed, will cause any contentention for memory bandwidth. I suspect that for any decent sized llr or genefer task, you would be running on at most 3 cores to maximize througput.

I have the similar 4570S, which turbos with 4 cores to 3.2 GHz. I assume the 4590S scales similarly so would run 3.3 GHz.

As a DDR3 system, I only have 1600 ram in it (low cost non-OC board) which can't efficiently support 4 cores. If you have a board that can support higher 2400 speeds, it then becomes viable. In a quick look DDR3 2400 ram isn't that expensive either so not as bad as I feared.

I didn't know all this when I put the system together... wonder if I can upgrade it cheaply enough to be worth it?

Andrew,

We discuss these below. The problem is the prohibitive price of the mobo.

Well, I installed one delta tfc1212de-pwm in the haf xb in the barn. Holy sweet mother of all that is good and decent. That thing is loud. Like tornado/air raid siren loud, with a slightly higher pitch. I can hear it well outside the barn. I can't imagine anyone putting one of these in the house.

That 250 cfm in a 120mm fan is pretty sweet. I'm keeping a 7990 below 50c with just air cooling on continuous full load. My eyes tear up whenever I get anywhere near it though.

I have been preoccupied with my first custom build and where the damn thing will not power up at all.

I picked up an extra power supply and the problem persists. I checked and double checked all the wiring but the problem still persists with no hint of life.

I have a sneaky suspicion the BIOS may be the culprit and which I am examining right now.

LOL It's nice to know Delta fans are still like that. They had quite a reputation when I first started on the PC building path, and many wouldn't ever have one. Yes, high flow, but high speed fan. If you have space the workaround in those days was to fit a bigger sized fan than you need on an adapter which directed the flow to a smaller area. Wonder if they still make those things?

I could make my own plenum if I had to (those electric metal shears come in real handy), but the largest "monster' delta fan I could find is 120mm, which conveniently (or inconveniently as it may be) fits the case exactly. I'm almost certainly going to have to get a regulator for that thing. And put two more on the front....

Fellow rodents,

I have my custom build almost all set to fly and after the BIOS was upgraded to the most recent release.

My only stumbling block is the installation of Windows 7 Pro 64-bit. I have a genuine copy burned onto a DVD and from where I boot (from the BIOS menu I choose USB CD/DVD in the boot sequence options).

The software loads fine until it is about to install the actual OS and where the infamous "A required CD/DVD driver device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.".

My hardware: i3 6300, MSI H110M Pro-VD, 2x4 Gb RAM

I have consulted Youtube and all of the various tips and tricks fail. Any suggestions?

Edit: %*^&%$@)& Microsoft!

What disk are you using? Did you get as far as the HD selection part?

Also, is there an option in the bios somewhere? I think I had to use a "windows 7 install mode" in there on my other MSI mobos also with Win7.

Edit: The Win7 install option is mentioned on page 18 of the downloadable manual for the mobo along with some other tips.

Edit: Was replying at the same time as mackerel.

Get to a command prompt; if you haven't been able to so far, I there are lots of little bootable programs which are designed to be put on a USB stick, and give you a command prompt with basic features, plus DVD-ROM drivers. Then do a copy *.* and put the whole DVD on to your HD/SSD. Then run the install program. I think that should work - and you can of course then delete the DVD from your HD after everything has installed.

The initial copy might be really slow, but of course the install should be fast.

Caveat and disclaimer. I am not a windows guy. At least for a long long time. /caveat. Need help installing OSX or openbsd? I can probably help better.

Any chance you have an nvme drive? I would guess since those things didn't exist when win7 was in production, the storage device drivers necessary weren't bundled. For all of you who remember the old nt 4.0 days with those oddball scsi drivers you needed, I recollect the process to be along the lines of finding the floppy driver, putting it on some media, probably a usb stick now a days, (fat32 I assume), and when setup asks if you need additional drivers, say yes, plug that in, and all should be good.

Just a shot in the dark.

Yes, within the BIOS I have Win 7 installation enabled whereas the other OS's (ex. Win 8) is/are disabled.

As for the disk, I have a DVD and where I burned the Win 7 ISO file onto using my i7 laptop with the help of Windows 7. This DVD is then used in an external USB DVD (Nec) for booting up. The initial Win 7 installation greeting loads just fine (where one selects language etc) and then proceed with the continue button. I get to a new screen where the installation starts and within seconds I get the very well-known error I described earlier. This is a known bug from Microsoft related to Win 7 (what else is new).

I will have a look at the downloadable manual for the tips you refer to (I already had the manual downloaded a few days ago).
